Schools have a load profile no other segment shares: strong daytime consumption during term, and then near-zero load through the longest, sunniest vacation of the year. Any honest school solar model has to deal with that directly rather than averaging it away.
What this segment needs
During term time a school is close to an ideal solar load — classrooms, fans, lighting, and labs all draw through the day. But April and May, the peak generation months in Karnataka, fall largely in the summer vacation when the campus is nearly empty. Almost all of that output is exported, so the value of your export arrangement matters far more for a school than for a typical commercial site.
Engineering considerations
Campuses usually have several blocks, sometimes on separate connections, with roofs of differing age, height, and construction. Older blocks may need structural assessment. Because a meaningful share of annual generation will be exported rather than consumed, the net metering and banking arrangement deserves close reading before capacity is fixed.
Karnataka context
Karnataka schools are typically on a commercial or institutional tariff rather than a residential one, so the avoided cost per unit is relatively high during term. How exported units are credited and whether they can be banked across billing cycles significantly changes the vacation-month economics, and these terms should be verified against current ESCOM rules.
Common mistakes to avoid
School projects are most often mis-sized because the vacation is not modelled:
- Sizing on term-time consumption without modelling the vacation months separately
- Assuming exported units carry the same value as consumed units
- Overlooking that the highest-generation months coincide with the longest holiday
- Skipping structural assessment on older campus blocks
- Scheduling installation during term rather than using the vacation window
What we recommend
Model term time and vacation as two separate cases rather than one annual average, and confirm exactly how exported units are credited before fixing capacity. Then use the vacation itself as the installation window — it is the one segment where the disruption problem solves itself.
Common questions
- What happens to generation during the summer holidays?
- With the campus largely closed, most output is exported to the grid and credited under net metering. Because this coincides with the highest-generation months, how your export is valued materially affects the overall return.
- Should we size the system for term time or the annual average?
- Model both. Sizing purely on term-time consumption tends to overbuild relative to what the annual economics support, given how much vacation output is exported.
- When is the best time to install?
- The vacation period. It removes disruption to teaching entirely and is usually long enough to complete installation and much of the commissioning.
- Do older school buildings need structural checks?
- Older blocks generally should be assessed before mounting. Campuses often span decades of construction, so the assessment may differ block by block.
- Can solar support our laboratories?
- During daylight, yes. If any laboratory equipment is outage-sensitive, that is a backup power question rather than a solar one and is handled separately.
